Title: Travis: Cope with ftpmirror.gnu.org being down

Sometimes builds fail because ftpmirror.gnu.org is down. With this change Travis will fall-back to downloading GNU parallel from main GNU FTP site instead if the mirrors fail. Failing that we don't bother with GNU parallel at all and gracefully degrade to running the tests in series.
